Application filed September 25, 1913. Serial No. 791,856.

To aZZ whom it may concern:

Be it known that I, EDWAR I. BRADDOCK, a citizen of the United States,residing in Viinchester, in the county of Middlesex and State ofltlassachusetts,have invented an Improvement in Wire-Bound Articles, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention relates to a wire-bound article and is herein shown asembodied in'a hollow article bound with wire hoops.

The invention is especially adapted for embodiment in a hollow,non-metallic article, such as a wooden firkin, tub, pail, loarrel, orthe like, and has for its object to provide a superior article at aminimum cost. To this end, the article to be bound,

which will be hereinafter referred to as a firkin, is employed as aformer upon which is wound a plurality of coils of wire in a heatedcondition and preferably covered with a coating of solder or like metalof a melting point which is relatively lower than the wire, so thatcontinuous convolutions of the coil of wire may be molecularly united toform a wire hoop, which is afhxed to the firkin by the contraction ofthe wire hoop when cooled. As the heated wire is wound upon the firkin,it chars or burns grooves in the outer surface of the firkin, whichserve to retain the wire hoop upon the tirkin against movementlongitudinally of the firkin, and the wire hoop may also be retained onthe firkin against movement, by means of spurs formed by bending thewire at the ends of the coil and driving them into the firkin. These andother features of this invention will be pointed out in the claims atthe end of this specification.

Figure 1 is an elevation of a firkin embodymg this invention. Fig. 2, avertical section of the firkin shown in Fig. 1. Fig. 3, a like sectionof the firkin wlth the wire hoops removed to illustrate the embedding ofthe wire. Fig. 4, a cross section on the line 44, Fig. 1. Fig. 5, adetail of one of the hoops, and Fig. 6, a detail in vertical section toillustrate the holing spurs, the section being taken on the line 66,Fig. 1.

In the present instance, I have illustrated a preferred form of theinvention, which comprises a firkin aof wood or other nonmetallicmaterial and such as now commonly made, which is provided with one ormore Wire hoops Z), herein shown as three in number. Each of the hoops bis composed of preferably a plurality of convolutions of iron, steel orother wire, having thereon a coating of solder of like non-corrosivemetal or alloy of metals of relatively lower melting point than thewire, and said convolutions are preferably arranged so that the coatingson adjacent convolutions contact for the length of the convolutions andunite and thereby molecularly join the convolutions of the wire coiltogether to form a hoop.

The first and last turns or convolutions of the wire hoop are providedwith bent and preferably pointed ends 0, d (see Fig. 6), which aredriven into the firkin' and form spurs or *mechanical holding devices,by which the Wire hoop is secured to the firkin against movementcircumferentially and longitudinally. The wire hoop b is also secured onthe firkin against longitudinal displacement by means of grooves 6, (seeFig. 3), Which are formed by the wire being wound in a heated conditionupon the firkin, and allowed to cool thereon.

As the heated Wire cools, the firkin and grips the same firmly, so thatif desired the contraction of the wire alone could be depended upon tosecure the wire hoop thereto, especially when the convolutions of thewire are molecularly united as above described. 011 the other hand, thespurs c, d, may be depended upon to secure the hoop on the firkin, inwhich case an uncoated wire may be used, but it is pre-' ferred toemploy both methods of securing the hoop on the firkin.

In the manufacture of the hooped firkins commercially, a suitablemachine will be provided in which the firkin is secured so as to berotated, and the wire will be led through a bath of molten soldercontained ina heated vessel, and either the said vessel or the firkinwill be'given a longitudinal motion, one with relation to the other, tocause the wire to be properly fed longitudinally on the firkin so as tolay the convolutions in contact with one another. Provision will itcontracts upon also be made for forming a spur at the beginning of thewire, which is driven into the iirkin, and for cutting the coiled wirefrom the straight portion, bending it to form a spur and driving thisinto the firkin.

The machine is not herein shown as it forms no part of the presentinvention and is not necessary for a proper understanding of the same.

It will thus be seen that automatically coopered.

It will further be observed that a strong firkin is obtained, inasmuchas it is bound by wire hoops, which are retained on the firkin by thecontraction of the wire and by the spurs or holding devices, which areintegral with the hoops. Furthermore, the wire hoops are materiallystrengthened by the union of the coating of solder on contiguousconvolutions.

B the term iirlrin as used in the claims, I desire to be understood asincluding not only the article commonly called a firkin, but also pails,tubs, barrels and like non metallic hollow articles. I

The staves comprising the firkin are temporarily held together by ametal band or ring, which is removed after the wire hoops have beenwound thereon.

lin coopering the firkin, the hoops may be formed simultaneous y orindividually.

Claims 1. A firlrin comprising a hollow non-metallic member havingthereon a wire hoop composed of a plurality of convolutions solderedtogether and embedded in the outer surface of said member with theconvoluthe firkin may be tions of the wire set and substantiallyrelieved from tension.

A firki'n comprising a hollow non-metallic member having thereon a wirehoop composed of a plurality of convolutions soldered together andembedded in the outer surface of said member with the convolutions ofthe wire set and substantially relieved from tension, said hoop havingbent portions which are embedded in the said member.

A firkin comprising a hollow, non-metallic member having thereon a wirehoop composed of a plurality of convolutions secured on the said memberby the contraction of the wire into a set condition substantially freefrom tension, substantially as described.

4:. A fir-kin comprising a hollow, non-metallic member having thereon awire hoop secured thereon by the contraction of the wire into a setcondition substantially free from tension and provided with bent endswhich are embedded in said member.

5. An article comprising a hollow member having thereon a wire hoopcomposed of a plurality of convolutions soldered together ant secured onthe said member by the contraction of the wire into av set conditionsubstantially free from strain, substantially as described.

In testimony whereof, I have signed my name to this specification in thepresence oi two subscribing witnesses.
